Octagonal abdominal muscles (six blocks)-/show/3v2y38cvlxl7rjz2 _ grenq ... html? ptag=vsogou

Note: Don't exercise your abdominal muscles too hard, or a muscle strain will last for a long time, but stick to it, or it won't work intermittently. If you don't practice your abdominal muscles every month or so, you won't see them. You should stick to it!
